I essentially replaced scrubber and bags, plus the fittings to clamp things down to the bag.
I retained the shell and BC. I used the same first stage, hoses, dosage block, and orifices.
It's very overpriced to make the transition. I think I spent a bit over $1200 for it, IIRC, plus the cost of doing a rebuild on the regulator, block, and mouthpiece. It's been a few years since I did that, so I'm a little fuzzy. However, I got the Atlantis for free, so it wasn't a bad deal in the end to make the unit a lot safer to dive. It'll be a nice platform to make into a mCCR when I get bored with my eCCR (like that'll ever happen

) Plus, I'd have to pry it away from my girlfriend, who took a liking to it...
Thanks Camerone. I already have the bags from the Dolphin, but I'd like to get the scrubber and probably all the fittings that you upgraded on yours.
